Carmine Di Salvo and Filippo Ferrari are arrested on the same day in Naples, but they seem to have nothing in common: Carmine dreams of becoming a professional hairdresser, despite being born into a Neapolitan Camorra family from which he would only like to escape so he can build an honest future; Filippo, on the other hand, is a promising pianist born into a very wealthy family in Milan who is on vacation in Naples.

Carmine was born into the world of crime and knows its rules perfectly, but for Filippo it's like having landed on another planet where even the language (Neapolitan dialect) is something he must struggle to understand.

To try to make the inmates understand that it is possible to radically change direction and live honestly are the director Paola Vinci, the commander of the penitentiary police Massimo Esposito, the educator Beppe Romano and the various guards.

[3] Produced by Rai Fiction and Picomedia, the series is filmed in the naval base on Via Acton in Naples.

Other filming locations in Naples include Maschio Angioino, the Caracciolo seafront, Galleria Umberto I, the Rione Sanità and Montesanto districts, Toledo underground station, the Centro direzionale, and Posillipo.

[15][16][17] For the third season of the series, however, the rights for broadcasting via streaming return to RaiPlay, which on February 1, 2023, publishes the first six episodes[18] thus anticipating the first viewing on live TV.

Stefano Lentini was awarded double platinum and two gold records, marking a unique achievement in the viral success of a film score for a series entirely produced in Italy[2].

Part of the music was performed by the RAI National Symphony Orchestra and mixed by Grammy Award-winning sound engineer Geoff Foster[4] [5].
